To all whom, it may concern:

Be it lmoun .nst l, ijaunmozv ELLIS, a citizen of tho United States, and rcs dcut of county of W icstci Lsrchmon lurk, liavc lllilllt'i certain and State of 110W and useful inventions Relating to Finish-Removers, of which the following is a specification.

This invention relates to finish removers and relates cspccisily to compositions of matter for the removal of paint, varnish, enamel, or other iinish costings without injury to the underlying surfscos or to the pcrsonci the operator, such compositions consisting essentially of on alcoholic or other loosening finish solvent with which a wax or waxy body has been suitably incorporated.

Loosening finish solvents, that is, solvents having a generally alcoholic character or act-ion in removers are very desirable for use in the removal of coatings consisting of shellac or other varnish gums and resins. Shellac, for instance, is very readily soluble in such volatile alcoholic or loosening finish solvents, although it "is not soluble m hen- 201 or sinlilsr hydronsshons whioh dccreasc this solvent power of tho loosening solvents in removers. Thsf'looscning finish solvents which preferably employed in this instance comprisc the strict alcohols, such as methyl (wood), cthyl (grain), propyl 'or other aliphatic or sromatic alcohol possessing neutral solvent properties forsuch resins or the functional equivalents of the strict alcohols in. rcmovsr including acetone, methyl ethyl lrctonc and other kotones, oil of acetone and also certain aldehydes', others and esters, such as amyl acetate, .for instance, many of chess solvents being used in their cheaper commercial forms, such as denatured alcohol, for example. W'a tor soluble aliphatic alcohols seem most desirable for this pinpose, particularly wood or grain alcohol in its denatured form, it dosirablc, although acetone is} also very elliciont with certain finishes.

The thickening and cvnporizstion retardmay consist of a wax or wax body pro v incorporated with the finis solvents on may comprise ccresin, Japan wax, beeswax or baybcrry wax, although various other waxes are useful with certain loosening solvent material. C ercsin is esgelatinous mass whlch has a very desirable thickening action, giving increased consistcncy to the remover. The composition may preferably be prepared by heating the loosening solvent material with the Wax until the latter has melted when the mixture is stirred vigorously and simultaneously; cooled as quickly as possible to the room temperature.

Other methods of preparation are, of course,

possible, separately and adding it to the previously warmed alcoholic solvent material. When prepared in this manner, the wax apparently remains to a certain extent in solution in a su ersaturated condition in which it is peculior y effective as a retarder of ova oration, only a small fraction of a. percent. 0 wax being needed for this urpose. The balance of the wax acts large y as a thickener, more or less consistency accordlng to the mover may comprise wood alcohol 90 gallons, acetone 10 pounds, and. sti mover may 100 gallons and ceresin wax 20 pounds. I This invention has been described in this case which is a divisional continuation of Ellis application 333,383, filed September 5,
